Box Gutter Framing

Unlike other gutters they are part of the roof structure.

Box gutter framing.

The foundation of most box gutters is wood that is then covered with thin sheet metal such as tin copper lead stainless steel or some other metal that will not readily corrode. Box gutters are composed of wood framing with a sheet metal lining normally copper stainless steel or galvanized steel. A box gutter is actually built into the bottom of the roof or into the roof overhang. Licensed sheet metal contractor call 323 405 4555 for estimates in la or oc.

The sheet metal creates a trough for the rain water to flow into the downspout. Provision is made in the design of the gutter to have a rain flow to the outlet with a maximum slope of 1 200 and a minimum of 1 400. Box gutters are essentially placed between parallel surfaces as in a valley between parallel roofs or at the junction of a roof and a parapet wall. They should not be confused with so called valley gutters or valley flashings which occur at the non parallel intersection of roof surfaces typically at right angled internal corners of pitched roofs.

A box gutter does not hang onto the edge of a roof or on the edge or side of a house as many modern pre formed metal gutters do. Copper gutter linings are most often built into wood framed supporting structures. The lining must be free to move. Although the copper lining conforms closely to the gutter frame profile it should not fit tightly.
